In my last post this same vase was pictured, the only difference is that in this photo I used black underglaze and painted the recessed areas. This vase is in its leather hard stage.
Oops. I suppose I should explain about the wax resist. Once the vase was leather hard I used hot wax and dripped it over the pot. I used a cheap 2 inch paint brush to accomplish this. Once the wax was dried I used a wet sponge and rubbed over the unwaxed parts of the vase. This created the recessed areas. I didn't know how I was going to fire it. The next day I was looking at it and I thought to myself "black underglaze," so I did that.
I still don't know how I'm going to fire this piece yet but I'm going to try this method of wax resist and "sponging" on another vase or two.
